Ice sheets melting faster than predicted

The pace at which the Greenland and Antarctic ice sheets are melting is "accelerating rapidly" and raising the global sea level, according to findings of a study financed by NASA.

The findings suggest that the ice sheets - more so than ice loss from earth's mountain glaciers and ice caps - have become "the dominant contributor to global sea level rise, much sooner than model forecasts have predicted".

This study, published on Tuesday, the longest to date examining changes to polar ice sheet mass, combined two decades of monthly satellite measurements with regional atmospheric climate model data to study changes in mass.

Well now a days we are facing one of the biggest problem of earth, and its global warming. Changing in climate is the usual thing that might happened and its very alarming for the environment as well as to the people with in earth.
